1. Robinair (15434) CoolTech Vacuum Pump – 2-Stage, 4 CFM
The Robinair 15434 CoolTech vacuum pump features power and capacity for a wide range of service applications, a high CFM rating for fast, thorough evacuation and a two-stage rotary design. Features: Iso-Valve – Isolates the pump from the system with just a quarter-turn; Gas Ballast – Moisture laden air passing through the pump mixes with relatively dry air to such a degree that compression does not cause condensation; Two-stage Design – Cleans the system more thoroughly than a single-stage pump, the second stage starts pumping at a lower pressure so you can pull a deeper, ultimate vacuum; Oil Drain Valve – Positioned at the bottom of the oil reservoir and angled for faster, more complete draining; Oil Fill Port – Makes adding oil simple since the port is accessible from the front or either side. The sight glass on the front of the pump shows you when enough oil has been added; Heavy-Duty Motor – High torque design for easy startup and efficient operation; Offset Rotary Vanes – Our proven design builds a powerful compression within the pumping chamber to reduce system pressure and vaporize moisture so it can be exhausted along with air; Molded Base – Durable polycarbonate base improves pump balance and minimizes vibration during operation; and Die-Cast Aluminum Housing – Cast aluminum housings make the pumps lightweight but durable.
